Thyroid cancers in Singapore 1968-'77

Y S Lee

    Tropical and Geographical Medicine
    |January 1, 1982
    PubMed
    Summary

    Thyroid cancer incidence in Singapore showed a slight decline in females, with papillary carcinoma being the most common type. Changes in environmental factors may influence thyroid cancer occurrence and histology.

    Area of Science:

    • Endocrinology
    • Oncology
    • Epidemiology

    Background:

    • Thyroid cancer incidence and histological types can be influenced by environmental factors.
    • Understanding trends in thyroid cancer is crucial for public health.
    • Singapore's Cancer Registry provides valuable data for epidemiological studies.

    Purpose of the Study:

    • To analyze the incidence and histological types of thyroid cancer in Singapore over a ten-year period.
    • To compare thyroid cancer trends between two distinct five-year periods.
    • To investigate potential associations between environmental changes and observed thyroid cancer patterns.

    Main Methods:

    • Retrospective analysis of thyroid cancer cases from the Singapore Cancer Registry (1968-1977).
    • Biopsy materials were reviewed and classified using the World Health Organization (WHO) Classification of thyroid cancers.
    • Crude incidence rates were calculated per 100,000 population per year for males and females.

    Main Results:

    • Overall crude incidence rates were 1 per 100,000 for males and 3 per 100,000 for females annually.
    • Papillary carcinoma was the predominant histological type, followed by follicular carcinoma.
    • A slight decline in female thyroid cancer incidence was observed between the two study periods, with an increasing papillary-to-follicular carcinoma ratio and a declining incidence of undifferentiated carcinoma.

    Conclusions:

    • Thyroid cancer incidence in Singapore showed a slight decreasing trend in females over the study period.
    • The increasing ratio of papillary to follicular thyroid carcinomas suggests a potential shift in histological patterns.
    • Environmental factors may play a role in modulating both the incidence and histological characteristics of thyroid cancers in Singapore.
